Power Supply Replacement
Power to the LED modules and fans (8 and 12 line models only) is provided by small 5-volt power
supplies. Each power supply can support two modules. In 0.7" displays, they are located on the
rear side of the LED module panel. The 1.2" and 2.1" displays have the power supplies mounted to
the back sheet within the display cabinet.
0.7" Displays
To remove a power supply that has failed, first take off the
LED module opposite of the failed power supply as
described in LED Module Replacement, above.
Each power supply is secured to the module panel with two
(2) 3x10 metric screws as shown in Figure 32. Use a #1
Philips head screwdriver to remove the screws.
